Geographic Regions

Like much of the African continent, South Africa's landscape is
dominated by a high plateau in the interior, surrounded by a narrow
strip of coastal lowlands. Unlike most of Africa, however, the perimeter
of South Africa's inland plateau rises abruptly to form a series of
mountain ranges before dropping to sea level. These mountains, known as
the Great Escarpment, vary between 2,000 meters and 3,300 meters in
elevation. The coastline is fairly regular and has few natural harbors.
Each of the dominant land features--the inland plateau, the encircling
mountain ranges, and the coastal lowlands--exhibits a wide range of
variation in topography and in natural resources (see fig. 7).

The interior plateau consists of a series of rolling grasslands
("veld," in Afrikaans), arising out of the Kalahari Desert in
the north. The largest subregion in the plateau is the 1,200-meter to
1,800-meter-high central area known as the Highveld. The Highveld
stretches from Western Cape province to the northeast, encompassing the
entire Free State (formerly, Orange Free State). In the north, it rises
into a series of rock formations known as the Witwatersrand (literally,
"Ridge of White Waters" in Afrikaans, commonly shortened to
Rand--see Glossary). The Rand is a ridge of gold-bearing rock, roughly
100 kilometers by thirty-seven kilometers, that serves as a watershed
for numerous rivers and streams. It is also the site of the world's
largest proven gold deposits and the country's leading industrial city,
Johannesburg.

North of the Witwatersrand is a dry savanna subregion, known as the
Bushveld, characterized by open grasslands with scattered trees and
bushes. Elevation varies between 600 meters and about 900 meters above
sea level. The Bushveld, like the Rand, houses a virtual treasure chest
of minerals, one of the largest and best known layered igneous
(volcanic) mineral complexes in the world. Covering an area roughly 350
kilometers by 150 kilometers, the Bushveld has extensive deposits of
platinum and chromium and significant reserves of copper, fluorspar,
gold, nickel, and iron.

Along the northern edge of the Bushveld, the plains rise to a series
of high plateaus and low mountain ranges, which form the southern edge
of the Limpopo River Valley in Northern Province. These mountains
include the Waterberg and the Strypoortberg ranges, and, in the far
north, the Soutpansberg Mountains. The Soutpansberg range reaches an
elevation of 1,700 meters before dropping off into the Limpopo River
Valley and the border between South Africa and Zimbabwe. The Kruger
National Park, which is known for its diverse terrain and wildlife,
abuts most of the north-south border with Mozambique.

West of the Bushveld is the southern basin of the Kalahari Desert,
which borders Namibia and Botswana at an elevation of 600 meters to 900
meters. Farther south, the Southern Namib Desert stretches south from
Namibia along the Atlantic coastline. Between these two deserts lies the
Cape Middleveld subregion, an arid expanse of undulating plains that
sometimes reaches an elevation of 900 meters. The Cape Middleveld is
also characterized by large depressions, or "pans," where
rainfall collects, providing sustenance for a variety of plants and
animals.

The southern border of the Highveld rises to form the Great
Escarpment, the semicircle of mountain ranges roughly paralleling South
Africa's coastline. The Drakensberg Mountains, the country's largest
mountain range, dominate the southern and the eastern border of the
Highveld from the Eastern Cape province to the border with Swaziland.
The highest peaks of the Drakensberg Mountains in KwaZulu-Natal exceed
3,300 meters and are even higher in Lesotho, which is known as the
"Mountain Kingdom."

In the west and the southwest, the Cape Ranges, the country's only
"fold mountains"--formed by the folding of the continental
crust--form an "L," where the north-south ranges meet several
east-west ranges. The north-south Cape Ranges, paralleling the Atlantic
coastline, include the Cedarberg Mountains, the Witsenberg Mountains,
and the Great Winterhoek Mountains, and have peaks close to 2,000 meters
high. The east-west ranges, paralleling the southern coastline, include
the Swartberg Mountains and the Langeberg Mountains, with peaks
exceeding 2,200 meters.

The Cape Ranges are separated from the Highveld by a narrow strip of
semidesert, known as the Great Karoo (Karoo is a Khoisan term for
"land of thirst"). Lying between 450 meters and 750 meters
above sea level, the Great Karoo is crossed by several rivers that have
carved canyons and valleys in their southward descent from the Highveld
into the ocean. Another narrow strip of arid savanna lies south of the
Great Karoo, between the Swartberg Mountains and the Langeberg
Mountains. This high plain, known as the Little Karoo, has a more
temperate climate and more diverse flora and fauna than the Great Karoo.

The narrow coastal strip between the Great Escarpment and the ocean,
called the Lowveld, varies in width from about sixty kilometers to more
than 200 kilometers. Beyond the coastline, the continental shelf is
narrow in the west but widens along the south coast, where exploitable
deposits of oil and natural gas have been found. The south coast is also
an important spawning ground for many species of fish that eventually
migrate to the Atlantic Ocean fishing zones.
